IMPROVEMENT IN THE IVIO'DE OF LAYING ROVING IN CANS.

Speoication forming part of Letters Patent No. 4,277,dated November 18,1845.

peculiar construction and arrangement of apparatus to be applied to thecarding-engine and other subsequent preparation machinerysuch as thedrawing, roving, or slubbing machinery-for the purpose of delivering ordepositing the slivers, drawings, slubbings, or rovings of cotton orother fibrous substances or material into the ordinary cans or otherreceptacles commonly used for such purposes, in order that the cans maybe caused to contain a much greater quantity of cotton, duc., and alsoto leave it in such a state that upon being withdrawn from the can inany subsequent process it may be freely delivered or unwound, andthepresence of any knots, lumps, or any other imperfections be avoided.The following description and accompanying drawingstaken together,constitute a full and exact specification of our invention.

Of the said drawings, Figure l is a horizontal view of this improvedapparatus as seen from above and attached to or placed in connectionwith the dofting end of a common carding-engine. Fig. 2 is an elevationof the same and shown in its relative situation in connection with theordinary tin can or receptacle placed to receive the sliver'of cotton,as usual. Fig. 3 is a vertical section taken through at aboutthe middleof the apparatus for the purpose of more clearly exhibiting its workingparts.

In the iigures the web of cotton is shown at A as passing from thedofiing cylinder through the usual cone or trumpet and be.

tween drawing or delivering rollers in the box B. From thence it isconducted along the trough or passage O to the apparatus about to bedescribed.

D is the tin can or common receptacle for the sliver, the said can beingplaced upon a plate-wheel ct ct, formed with a vertical rim or otherproper contrivance to receive the can fand insure its correct positionwith respect to W the delivering apparatus. This plate-wheel ct c ismounted upon a central stud or pin b,

affixed to the foundation or bottom plate c c, y

and from this plate rise two vertical columns .fl d, carrying the topplate to box e e, placed some distance above the mouth of the tin can Dand supporting the improved delivering apparatus. This apparatus,constituting the first feature of novelty in these improvements, isconstructed and operates as fol llows: A small pulley ct or otherconnecting- `gearing is iixed upon a shaft f, suitably fmounted upon ornear the bottom plate c o. :To this pulley motion is to be communicatedvfrom any convenient driving part of the carding-engine or othermachinery. This shaft f has a miter-wheel g, which gears with a similarwheel h upon a vertical shaft i.

Upon the upper end of this vertical shaft t a spur-pinion lo is keyedand engages with a Aspur-wheel Z, formed around the periphery of acircular box m, which box is properly supported by and so as to revolvewithin the stationary upper plate e e. This stationaryv upper plate c ehas a horizontal circle of beveled teeth o formed on its surface, intowhich a beveled pinion p gears.

q q are a pair of calender-rollers, one of which is made fast to thebevel-pinion or is placed yupon the same shaft with it. The said rollersshould be coupled together by a pair of pinions taking into each other,one of which is seen at r, Fig. 3. The rollers q q and bevelpinion p aremounted and turn loosely upon studs or axles lixed in the bracket s,from whose top an arm t extends and carries the trumpet t, that conductsthe sliver A to the rollers. The bottom plate m has also a spout oropening n for the same purpose.

From the rotary movements of the parts. described it will be seen thatthe sliver A will be drawn down by the calender-rollers q q anddelivered through the spout n.- Now, in order that the slivers,drawings, slubbings, or rovings may be deposited in the can in a certainnovel and peculiar manner, and which will allow of their subsequentdeposit without injury and their being afterward readily withdrawntherefrom without entanglement, it must be observed that the deliveryapparatus is placed eccentric with respect to the center or axis of thereceiving-can, and also that the can is caused to revolve very slowly inthe contrary direction to that of the delivering or depositingapparatus, which is eilected by means of the Worm o, placed upon thedriving-shaft f and suitably connected by a slow train of gearing w a:to the spur-Wheel round the bottom of the can-receiver Q Q. The effectof the revolutions of the delivery apparatus and the can is that thesliver is deposited in eccentric helices, which are Wound one above theother around the interior of the can in a similar manner to thatrepresented in the top view of the can of sliver at Fig. 4 and in sideview at Fig. 5, each of the apparent divisions y z, Fig. 5, indicatingone entire revolution of the can and so many of the revolving deliveringapparatus as shall be required to form eccentric helices entirely aroundthe interior ot' the can. Then the can or receptacle has thus becomeloosely filled with slivers, drawings, slubbings, or rovings, thehelical column Will extend upward and at length rise against the underside of the box m, and as the revolutions of the apparatus continue thecotton will still be drawn, deposited, and packed in the can or otherreceptable until any desired quantity has accumulated therein before itmay become necessary to remove the can from the machine.

lVe would here remark that in such cases where a very great weight ofcotton is thus put or pressed into the can the elasticity of it onremoval of the can would cause it to rise some distance above the top ofthe can. To prevent accidents or injury to the mass by reason of itsfalling over the side of the can, it is advantageous to have a movabletelescopic tube fitted upon the upper part of the can, or insteadthereof a skeleton frame of side rods may be elevated around the top yof the can, and thus prevent the sliver falling over sidewise as itrises.

lVith :respect to the process of slubbing or roving we would remark thatin those instances where it is not desirabe or convenient to employ thisapparatus to such process We propose to take the slubbings or rovingsfrom ordinary bobbins and double them and by this apparatus deposit themin cans or other receptacles precisely in the same form, placing thecans behind the roving or spinning machine instead of using bobbins, ascommonly done.

We would further observe that in those instances Where it may bepreferred to deposit the sliver directly upon a false bottom of the can,which will recede as the sliver accumulates, the calenderollers may bedispensed with by placing the false bottom against the box m, which willthen be sufficient to cause the sliver to be properly deposited, and,lastly, that in such instances where the cans orreceptacles are requiredto be of an oval, square, oblong,or any other form the sliver, drawing,slubbing, or roving may be deposited with a similar effect merely bysuitably traversing or revolving the plates on which the calender ordelivering rollers are placed, the receivers or cans being eitherstationary or in motion.

Another modilication ot the same invention is that in which the can orother receiving-vessel is made stationary. In suoli case the deliveringapparatus is not only to be made to revolve or operate in the man ner asabove described, but it should also have such a circular motion impartedto it as Will cause it to lay the sliver around the interior of the canin eccentric helices, as exhibited in Fig. 4,
